This is the third of three GigaPans I took on the 21st of December 2008 of the Twelve Apostles. The second picture was taken nearly 180 degrees around from this one.

Since I couldn't put it any more concisely, here is a description from www.visitvictoria.com The Twelve Apostles are giant rock stacks that rise majestically from the Southern Ocean and are the central feature of the rugged Port Campbell National Park. The Twelve Apostles are the remnants from constant erosion of the limestone cliffs of the mainland that began 10-20 million years ago. The stormy Southern Ocean and blasting winds gradually eroded the softer limestone, forming caves in the cliffs. The caves eventually became arches and when they collapsed rock stacks up to 45 metres high were left isolated from the shore.
The Twelve Apostles are located just east of Port Campbell, along the Great Ocean Road. - visitvictoria.com
